Amadivayisi amancane nokusebenza kahleamachweba
Abacwaningi be-REnsselaer Polytechnic Institute Abaphenyi badale aIdivayisi ye-LaserLokho kuphela ububanzi bezinwele zomuntu, ezizosiza izazi zesayensi zesayensi zifunde izakhiwo eziyisisekelo zendaba nokukhanya. Umsebenzi wabo, enyatheliswa kumaphephabhuku esayensi ahlonishwayo, futhi bangasiza ekuthuthukiseni ama-lasers asebenza kahle ukuze asetshenziswe emasimini aqala ngomuthi.
Le khasii-laserIdivaysi yenziwa ngento ekhethekile ebizwa nge-photoc topological insulator. Ama-insulators e-Photonic Topological akwazi ukuqondisa ama-photons (amaza nezinhlayiya ezakha ukukhanya) ngezindawo ezikhethekile ngaphakathi kokuqukethwe, ngenkathi uvimbela lezi zinhlayiya ukuba zingasakazeki. Ngenxa yale mpahla, ama-insulatorical opopayi anika amandla ama-photon amaningi ukuthi asebenze ndawonye. Lawa madivaysi nawo angasetshenziswa njenge-topological "hantum simulators," evumela abaphenyi ukuthi bafunde ama-qunomena - imithetho yemvelo eqondisa izinto ezikalini ezincane kakhulu - ngama-mini-labs.
"TheI-Photonic topologicalI-insulator esayenza ihlukile. Isebenza emazingeni okushisa asekamelweni. Lokhu kuphumelela okukhulu. Phambilini, ucwaningo olunjalo lungenziwa kuphela kusetshenziswa imishini emikhulu, ebizayo ukuze kuzitholile ezintweni ezipholile ku-vacuum. Ama-labs amaningi wokucwaninga awanalo lolu hlobo lwemishini, ngakho-ke idivaysi yethu inika amandla abantu abaningi ukuba benze lolu hlobo lokucwaninga kwe-physics okuyisisekelo kwelebhu kanye ne-Engineering kanye nomlobi omkhulu wesifundo. Isifundo sasinosayizi omkhulu wesampula, kepha imiphumela iphakamisa ukuthi umuthi wenoveli ukhombisile ukusebenza kahle kokuphamba lokhu okungavamile. Silangazelela ukuqinisekisa lokhu kuqinisekisa le miphumela ekuvivinyweni kwemitholampilo okuzayo futhi sikwazi ukuholela ezikhethweni ezintsha zokwelashwa kweziguli ngalesi sifo. " Yize usayizi wesampula wocwaningo ubuncane, okutholakele kusikisela ukuthi lo muthi wenoveli ukhombisile ukusebenza okubalulekile ekwelapheni lokhu kuphazamiseka kwezakhi zofuzo okungavamile. Silangazelela ukuqinisekisa lokhu kuqinisekisa le miphumela ekuvivinyweni kwemitholampilo okuzayo futhi sikwazi ukuholela ezikhethweni ezintsha zokwelashwa kweziguli ngalesi sifo. "
"Lokhu futhi kuyisinyathelo esikhulu phambili ekuthuthukisweni kwama-lasers ngoba umkhawulo wedivaysi yokushisa egumbini lokushisa (inani lamandla adingekayo ukulenza lisebenze) liphansi amadivaysi aphansi aphansi," abaphenyi bangeze. Abacwaningi beRenselaer Polytechnic Institute basebenzise inqubo efanayo esetshenziswe embonini ye-semiconductor ukwenza ama-microchips ukudala inhlobonhlobo yabo, okubandakanya ukufaka izinhlobo ezahlukene zezinto zokwakha, kusuka ku-athomu kuya kwezinga le-molecular, ukudala izakhiwo ezinhle ngezakhiwo ezithile.
Ukwenzaidivaysi ye-Lasers, abacwaningi bakhulisa amapuleti e-ultra-mncane eSelenide Halide (ikristalu enziwe nge-cesium, ehola kanye ne-chlorine) nama-polyers afakwe amasekhethi kuwo. Basebehlabe amapuleti amapuleti ama-crystal phakathi kwezinto ezahlukahlukene ze-oxide, okuholela entweni ecishe ibe ngama-2 microns aminyene futhi ama-100 ama-microns ubude nobubanzi (ubukhulu bezinwele zomuntu yi-microns eyi-100).
Lapho abacwaningi bekhanyisa i-laser kudivayisi ye-lasers, kuvela iphethini ye-luminous triangle esibonakalayo sedizayini yezinto ezibonakalayo. Iphethini inqunywa ukuklanywa kwensiza futhi kungumphumela wezimpawu zenkolo ze-laser. "Ukwazi ukutadisha izinto ze-qunomena egumbini lokushisa lasekamelweni kuyithemba elijabulisayo. UProfessor Bao's Instative Worcing ukhombisa ukuthi ubunjiniyela bezinto ezibonakalayo bungasisiza ukuba siphendule eminye yemibuzo emikhulu kwisayensi. " I-REnsselaer Polytechnic Institute Engineering dean uthe.
